[mapserver-users] geometries disappear while zooming (leene)

Hi Mark,
thank you, this works :-)

Leene,

It could be that you updated a shapefile without updating the spatial 
index.   Check your data folder and look for a qix file with the same 
name as your shapefile.  If the date is older than your shapefile you 
will either need to delete it, or update it using shptree http://mapserver.org/utilities/shptree.html.

>> Hey,

>> Another problem is if some points of the polygon are outside of the current

>> Are there any other suggestions?
